In Germany May 6, 1935 4 Claims. (01. 15-200 Several embodiments of theinvention are illustrated in the accompanying drawing, in which Figure lis a top view of line A-B, of Fig. 1;

gitudinal section on the line E-F, of Fig. 3; Fig. 5, a top view ofanother embodiment of the in-, vention; Fig. 6, a top view of anadditional plate forming part of the wringing means.

Referring to shown in Figs. 1 and 2 comprises two plates l and 2 made ofmetal, aluminum, etc. Corresponding to the shape of the wringer plate 3,the front end of both plates i and 2 is rounded off in a semicircle andthe rear end thereof provided, respectively, with a flange 4 and 5. Thelower flange has holes for the reception of the screws '6 for securingthe device to buckets, tubs, etc. The actual wringer plate 3 of circularform consists of rubber and is provided with a hollow space i and acentral opening 8. The hollow space 1 is open at the circumferentialsides of the plate 3 and closed. towards the hole 8 so as to form a wallaround the latter. Within the space 1 spiral springs 9 are radially.arranged, one endv of which is secured to the frame of the device bymeans of the pin ill and the other end abuts against the wall of theopening 8. The location and disposition of said springs within theopening being thus so as to exert pressure upon the surrounding wall ofthe opening 8, thus tending to close the said opening, whilst on anarticle be-' ing drawn through the said opening said springs offerresistance to ready expansion of the opening. The wringer plate 3 issecured within the frame by the grub screws Ii. Both plates l and Zhavea central round opening I! whose diameter is larger than that of theobjects to be wrung out by being passed through the apertured wringerplate 3.

While an article is wrung out by being drawn through the aperturedwringer plate 3 the spiral the drawing, the construction tured wringermember comprising springs 9 press against the wall of the centralaperture and thus increase the pressure.

Referring to Figs. 3 to 5, a modification of the cuts H, a cloth to bedrawn-through. In order to prevent ready tearing of the material of thewringer member 3 at the ends of said cuts edge of which slot-likeaperture may also be reinforced by an annular bead to prevent readytearing of the wringer member material on a cloth being drawn throughsaid aperture.

At a convenient distance from the edge of the aperture, and according tothe shay-T thereof, i. e.

cloth drawn through said aperture.

I claim:

1. A device for wringing wet fabrics consisting of 'a frame with anapertured wringer member of resilient material mounted therein, saidwringer member comprising a disc with a fabric receiving aperturetherein and auxiliary means disposed about the fabric receiving aperturefor augmenting the pressure of said resilient wringer member upon thearticle to be wrung out during the wringing operation due to theexpansion-of said aperture in use and means for supporting said frame.

2. A device for wringing wet fabrics consisting of a frame with anapertured wringer member of resilient material mounted therein, saidapera disc with a fabric receiving aperture therein and having a hollowspace open on the peripheral sides of said disc and closed towards theaperture to form a wall around the latter, auxiliary spring meansdisposed about the fabric receiving aperture for the article to be'augmenting the pressure upon wrung out and located in said hollow space,said spring means being secured onto the frame and position byvulcanizing, in the material around the aperture of the wringer member,thus tending to prevent ready expansion of the central wringer memberportion encircled by said spring means, and means for supporting saidframe.

4. A device for wringing wet fabrics consisting of a frame with anapertured wringer member of resilient material mounted therein, theaperture of said wringer member being substantially closed by prongsproduced by cuts emanating from the centre of the aperture of thewringer member towards the periphery and of the length ,of the radius ofsaid aperture, auxiliary spring means for augmenting the pressure ofsaid wringer member upon the article to be wrung out, said auxiliaryspring means comprising a, spiral spring arranged about said aperture,and

means for supporting the frame.
